"Ext. Generator Visa Error!" Error with Visa driver provided with installation (very
unlikely)
Overloading
At a reference level of -10 dBm and at an external generator output level of the same
value, the R&S
FSV/A operates without overrange reserve. That means the
R&S FSV/A is in danger of being overloaded if a signal is applied whose amplitude is
higher than the reference line. In this case, either the message "RF OVLD" for over-
load or "ADC OVLD" for exceeded display range (clipping of the trace at the upper dia-
gram border = overrange) is displayed in the status line.
Overloading can be avoided as follows:
●
Reducing the output level of the external generator ( "Source Power" on page 384
in "External Generator > Measurement Configuration")
●
Increasing the reference level ( Reference Level in the "Amplitude" menu)
6.2.4.3 External generator control settings
Access : [INPUT/OUPUT] > "External Generator Config"
The "External Generator" settings are available if the R&S FSV/A External Generator
Control option is installed. For each measurement channel, you can configure one
external generator. To switch between different configurations, define multiple mea-
surement channels.
For more information on external generator control, see Chapter 6.2.4.2, "Basics on
external generator control" , on page 371.
